"Just dodge it"
Is a terrible excuse.
If the person is good at the champion they play, they will know how to land their skill shots. They are called skill shots, because they require skill to use. If the person playing said champion has lots of skill with that champion, it's really hard to dodge. They will be able to predict the speed or where you'd probably run. Saying "just dodge it" is a terrible excuse.
I can understand it for some things, but when it comes to those champion who only need to land one. They could be bad all game but that one time where it matters is completely game changing.
Saying "just dodge it" is almost as bad as saying "stop dying". People don't just walk into skill shots for fun.
